So, dunno if anyone else is still doing help for this but I can get the two to work together for the most part except for one glaring issue, Hair mods installed with DAImm (aswel as armor mods like the TMM series (esp the starter one)) don't work when the game is launched through frosty and I can't find that issue anywhere else (Or a solution to it) any help would be amazing.
And as for the Lore Friendlyness or realism of it, when you are using a magic staff you are using it as a Focus, like a wand, who's to say that your sword shield mace hammer or axe doesn't function exactly the same? as a Focus for your Magicka.
why Not just allow Spells to be assigned to (default key) 'Z' like shouts but have a script run so that you have to charge it like normal and it uses your left/off/shield hand?
